<h3 id="rationale">Rationale:</h3>
<p>The here document delimiter will not be recognized if it is
indented.</p>
<p>You can fix it in one of two ways:</p>
<ol>
<li>Simply remove the indentation, even though this may break
formatting.</li>
<li>Use <code>&lt;&lt;-</code> instead of <code>&lt;&lt;</code>, and
indent the script with tabs only (spaces will not be recognized).</li>
</ol>
<p>Removing the indentation is preferred, since the script won't
suddenly break if it's reformatted, copy-pasted, or saved with a
different editor.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>If the line was supposed to be a literal part of the here document,
consider choosing a less ambiguous token.</p>
